The idea of the theme is good, but I did not understand what exactly I should do during the gameplay. Should I collect all the yellow circles? All the cyan squares? Which one is the key? It was confusing. If there was some explanation of the objectives of each level, or what each thing does, it would be more clarifying. As for the mechanics, the ability to close the eyes is interesting, and could be more explored, like if you close your eyes the Medusa doesn't follow you for long, or something in that way. At some point in level 2, some numbers appeared on the screen, I believe they were coordinates for the Medusa's position(?), I don't know what they meant, but having those informations and objectives more clear or intuitives would be great.
